Quality Of Continuous Casting Slab Crystallizer And Control System Research

In order to realize the casting billet hot state or directly with furnace, rolling must produce don't need surface treatment of high quality casting. Mould is very important parts, caster is a force of water cooling the bottomless ingot mould. Call it the "heart" of continuous casting equipment. Continuous casting mould oscillation is the most basic characteristics of conventional continuous casting. The quality of the products of steel market demand more and more high, to mould the vibration of the proposed rule again and again, as it was the requirements of mould oscillation rule from the evolution of the rectangular speed laws for popular now step by step a nonsinusiodal speed laws.This paper based on the actual production need, because the mould quality negative slippage time by crystallization, the influence of negative slippage theory, according to the theory and vibration is negative surge wave relations, so as to give sine vibration and the sine of vibration displacement and speed expression. Design hydraulic servo system, and each element in the system is the transfer function of the system, so as to get the transfer function. Through MATLAB system stability of judgment. PID parameters directly influence the set the whole control system is good or bad, through the critical ratio method of the parameters of PID setting, get the satisfactory PID parameters. MATLAB simulation of control system, the contrast of several simulation curve, verify the feasibility of the control system. The program design, and PLC and thus for the field experiment. In the process of field experiment data collection, in mould oscillation control of the stability of the system operation, the use of VISION data collection, the data collected MATLAB/GUI for data shows, get and the sine vibration of sine displacement and acceleration curve, and from X, Y, Z three directions in the design of the control system of inspection.At present, the actual production of the applications of the mould oscillation control system is the most foreign products, mould of foreign non-sinusoidal vibration research has matured and domestic research in just the start stage, so independent research open mould of a non sinusoidal vibration control system, and the research and development of new vibration waveform is significant.
